Window system provided with blind for solar photovoltaic power generation

Abstract

The present invention relates to a window system provided with a blind for solar photovoltaic power generation. In the window system of the present invention, a blind provided with solar cells is installed in a space between indoor side windows and outdoor side windows slidably coupled to the inner surfaces of a window frame. With such a configuration, the window system is easy to install and maintain. The window system of the present invention includes a window frame 10; indoor side windows 21 and outdoor side windows 23 slidably coupled to the inner surfaces of the window frame 10; and a blind 100 for solar photovoltaic power generation installed in a space S between the indoor side windows 21 and the outdoor side windows 23.

The invention claimed is: 
     
       1. A window system, comprising:
 a window frame; 
 indoor side windows and outdoor side windows slidably coupled to inner surfaces of the window frame; and 
 a blind for solar photovoltaic power generation installed in a space (S) between the indoor side windows and the outdoor side windows, 
 wherein the blind comprises:
 a main body fixed to an upper inside of the window frame; 
 a plurality of blades installed below the main body and each having one side on which solar cells are provided, wherein the blades are connected via a driving line and arranged to be spaced apart from each other; and 
 an electric condenser electrically connected to the blades and responsible for storing electric energy generated by the solar cells, and 
 
 wherein, on an outdoor side of the window frame, a barrier made of various materials is installed at a lower section (B) of an opening of the window frame; and among the blades arranged to be spaced apart from each other in a vertical direction in the opening of the window frame, only the blades located in an upper section (A) of the opening of the window frame where the barrier is not installed are provided with the solar cells and wherein the blades in the lower section where the barrier is installed do not have solar cells, and the barrier extends between two vertical members of the window frame. 
 
     
     
       2. The window system according to  claim 1 , wherein the blind further comprises an inverter electrically connected to the blades and responsible for converting direct current energy generated by the solar cells into alternating current energy. 
     
     
       3. The window system according to  claim 1 , wherein the main body is fitted in a snap-fit manner to a fixed bracket installed on an upper inner surface of the window frame. 
     
     
       4. The window system according to  claim 1 , wherein an actuator for automatically operating the blades on a sunny day or during periods of high insolation is provided inside the main body,
 wherein the actuator comprises a light sensor for detecting an amount of sunlight; and 
 a driving motor for rotating, in a forward or reverse direction, a winding roller for winding the driving line to automatically adjust folding or unfolding and angles of the blades based on a signal detected by the light sensor. 
 
     
     
       5. The window system according to  claim 1 , wherein each of the blades comprises a base layer formed of any one of a printed circuit board (PCB), polyvinyl chloride (PVC), acrylic styrene acrylonitrile (ASA), aluminum, and wood;
 the solar cells laminated on an upper portion of the base layer; and 
 an epoxy resin layer laminated on upper portions of the solar cells. 
 
     
     
       6. The window system according to  claim 1 , wherein each of the blades comprises a base layer formed of any one of a printed circuit board (PCB), polyvinyl chloride (PVC), acrylic styrene acrylonitrile (ASA), aluminum, and wood;
 the solar cells laminated on an upper portion of the base layer; 
 an ethylene-vinyl acetate (EVA) resin layer laminated on upper portions of the solar cells; and 
 a polyethylene terephthalate (PET) film layer or thin glass layer laminated on an upper portion of the EVA resin layer. 
 
     
     
       7. The window system according to  claim 1 , wherein each of the blades comprises a base layer formed of any one of a printed circuit board (PCB), polyvinyl chloride (PVC), acrylic styrene acrylonitrile (ASA), aluminum, and wood;
 the solar cells laminated on an upper portion of the base layer; and 
 an injection-molded cover disposed on upper portions of the solar cells to fix positions of the solar cells. 
 
     
     
       8. The window system according to  claim 1 , wherein the blades are connected via flexible printed circuit board (FPCB) wires capable of being flexibly folded or unfolded. 
     
     
       9. The window system according to  claim 1 , wherein, the barrier is made of glass. 
     
     
       10. A window system, comprising:
 a window frame; 
 single-pane or double-pane windows slidably coupled to inner surfaces of the window frame; and 
 a blind for solar photovoltaic power generation installed at an indoor side of the window frame, 
 wherein the blind comprises:
 a main body fixed to an upper inside of the window frame; 
 a plurality of blades installed below the main body and each having one side on which solar cells are provided, wherein the blades are connected via a driving line and arranged to be spaced apart from each other; and 
 an electric condenser electrically connected to the blades and responsible for storing electric energy generated by the solar cells, and 
 
 wherein, on an outdoor side of the window frame, a barrier made of various materials is installed at a lower section (B) of an opening of the window frame; and among the blades arranged to be spaced apart from each other in a vertical direction in the opening of the window frame, only the blades located in an upper section (A) of the opening of the window frame where the barrier is not installed are provided with the solar cells, and wherein the blades in the lower section where the barrier is installed do not have solar cells, and the barrier extends between two vertical members of the window frame. 
 
     
     
       11. The window system according to  claim 10 , wherein the barrier is made of glass.
